Application filed November 10, 1916. Serial No. 130,5622.

To all whom itmay concern."

Be it known that l[, FRANK JoNEs, a citizen of the United States, and a resident of Oakland, in the county of Alameda and State of California, have invented a new and Improved Grease-Retainer, of which the following is a full, clear, and exact descri tion.

y invention relates to a contrivance which is designed to prevent the passage of grease from the diflerential casing to the brake drums through the axle housing.

An object of the invention is to provide a simple, inexpensive and eficient device which can be easily and quickly applied between the housing and axle near the bearing of the axle in the housing.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

1n the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figui'e 1 is a fragmentary elevation and section of a rear axle of aFor'd car provided with an embodiment of my invention;

Fig. 2' is an-elevation of the barrel; and Fig. 3 is an end elevation of the barrel.

Before proceeding to a more detailed description of my invention it must be clearly understood that although the description and the 'disclosure shows the device as applied to the Ford car it is by no means limited'in its application to the structure of a' Ford car, as substantially without any modification 1t may be as well appliedto any other'structure of a rear axle".

Referring to the drawings, 4 is the barrel which is cylindrical in shape, having a lateral exterior flange 5 at one end and an annular inward flange 6 at the other end. The

flange 5 is of an external diameter substan-.

tially equal to -the inner diameter of the roller-bearing. housing 7. The aperture of the annulanfiange 6 is sufficiently large to prevent the rotation of the barrel.

9 provided in the barrel 4. Said lining can be made of any suitable yielding material but it is preferably made of felt. A felt Washer 10 is interposed between the flange 5 and the ring 11 which reinforces the connection between the axle housing and the drum-plate support 12, which also reinforces the housing at the roller bearing.

The barrel 4 has a plurality of beads or strips 13 which are adapted to engage the ring 11 and which in cooperation with the rivets which join the ring and the housing,

To facilitate the removal of the barrel the annular flange 6 is provided with notches 14 through which a tool may be passed to grip the barrel and pull it out of the housing.

In cases where the axle 8 is rough within the lining 9 the axle has a tendency to grip and revolve the lining. To prevent this, a ferrule 15 is fitted tightly on the axle. The outer surface of the ferrule is made smooth so as not to grip'the lining.

The grease, which has a tendency to follow the axle, is barred from passing to the roller bearing 16 by the lining 9. It is also prevented from passing about thebarrel to the roller bearing by the washer 10 which is interposed between the flange and the ring 11. It is self-evident that the length of the lining 9 may be varied in accordance with the conditions. It would require a comparatively short lining to positlvely prevent grease from passing between such a lining and an axle.

While 1- have described the principle of operation, together with the device which if now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such chan es may be made as are within the scope of the appended claim.

I claim:

Tn combination with a rear axle and housing therefor of an automobile, a grease container comprising a cylindrically shaped barrel presenting an exterior lateral flange at one end and an annular inward flange at the other end, a felt lining fitting snugly into the barrel and abutting against the annular flange, said felt lining adapted to fit snugly over the axle, a ferrule having a smooth exterior surface adapted to fit on the axle if the surface of the axle which fits in the felt lining is rough, means for preventing the rotation of the barrel in the housing, and a felt Washer on the barrel at 10 set forth.

FRANK JONES.
